This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections. Thesis: S.M., Massachusetts Institute of Technology, Department of Aeronautics and Astronautics, 2019 Cataloged from student-submitted PDF version of thesis. Includes bibliographical references (pages 97-100). A gap exists in the design space for aircraft mass and speed: no flight vehicles with a mass of less than 10 kg and speed greater than 100 m/s are available. The small, fast "Firefly" flight vehicle is being developed to explore the capabilities and challenges for aircraft in this gap. The compact Firefly aircraft is configured around a long-endurance, end-burning solid rocket motor that provides 2-3 minutes of powered flight. Challenges exist for manufacturing solid rocket motors for small, fast aircraft such as Firefly. Achieving desired motor performance requires a void-free propellant grain and thermal liner and a strong propellant-to-liner bond. However, observations and tests following several motor manufacturing attempts have revealed voids in the propellant and liner and delamination at the propellant-to-liner interface. Manufacturing defects such as these have led to large increases in chamber pressure and thrust during a static fire test of a motor. This thesis describes the development and implementation of manufacturing methods for slow-burning, long-endurance motors used in small, fast aircraft. Innovative tooling and rigorous procedures have been developed to help ensure the consistent production of a long-endurance solid rocket motor. Successful static firings of a test motor validate the effectiveness of many of the developed manufacturing methods. by Kelly J. Mathesius. S.M. S.M.
